Abstract
OBJECTIVE The current study aimed to characterise the food profile of Yanomami indigenous children according to the degree of food processing and its associated factors. DESIGN This is a cross-sectional study with Yanomami indigenous children aged 6 to 59 months. Socio-demographic, maternal and infant data were collected through a standardised questionnaire. The food profile was obtained by using a list of thirty-four foods to verify the child's consumption of these foods on the day preceding the interview. Foods were classified according to the degree of processing based on the NOVA system (in natura or minimally processed, processed culinary ingredients, processed and ultra-processed). In natura and minimally processed foods were subdivided into 'regional' and 'urban' foods. Poisson regression analysis was applied to estimate the associated factors according to the 90 % CI. SETTING Three villages (Auaris, Maturacá and Ariabú) in the Yanomami indigenous territory, in the Brazilian Amazon. PARTICIPANTS In total, 251 Yanomami children aged 6 to 59 months were evaluated. RESULTS The prevalence of consumption of 'regional' and 'urban' in natura or minimally processed foods was 93 % and 56 %, respectively, and consumption of ultra-processed foods was 32 %. Ultra-processed food consumption was 11·6 times higher in children of Maturacá and 9·2 times higher in Ariabú when compared with the children of Auaris and 31 % lower in children who had mothers with shorter stature. CONCLUSION Despite the high frequency of consumption of in natura and minimally processed foods, the consumption of ultra-processed foods was substantial and was associated with demographic and maternal factors in Yanomani indigenous children under 5 years of age.

Abstract
The maintenance of postural balance can be influenced by the lifestyle of a population. This study aimed to determine the electromyographic activity of the masseter and temporalis muscles during mandibular tasks and habitual and non-habitual chewing in indigenous individuals to reveal the differences among white Brazilian individuals. Sixty Brazilians (18 and 28 years) were divided into two groups: 30 Xingu indigenous individuals and 30 white Brazilian individuals, with 20 men and 10 women in each group. The individuals were assessed using the normalized electromyographic activity of mandibular tasks (rest, protrusion, right and left laterality) and electromyographic activity of masticatory cycles in habitual (peanuts and raisins) and non-habitual (Parafilm M) chewing. Data were analyzed using Student's t-test (p < .05). Comparisons between the groups demonstrated significant differences. Indigenous individuals group presented a decrease in the normalized electromyographic activity of the masticatory muscles during mandibular rest [right masseter (p = .002) and left masseter (p = .004) muscles]. There was increase in the normalized electromyographic activity during protrusion [left temporal (p = .03) muscle]. There was increase in the electromyographic activity during chewing: peanuts [right masseter (p = .001), left masseter (p = .001) and right temporal (p = .01) muscles], raisins [right masseter (p = .001), left masseter (p = .002), right temporal (p = .008), left temporal (p = .01) muscles] and Parafilm M [left masseter muscle (p = .05)]. From the findings of this study, we concluded that in the comparison between indigenous and white individuals, positive changes were observed in the electromyographic pattern of the masticatory muscles in the mandibular postural conditions, with greater masticatory efficiency in the indigenous group.

Abstract
BACKGROUND Globally, diarrhea is the second leading cause of death among children under five. In Brazil, mortality due to diarrhea underwent a significant reduction in recent decades principally due to expansion of the primary healthcare network, use of oral rehydration therapy, reduced child undernutrition, and improved access to safe drinking water. The First National Survey of Indigenous People's Health and Nutrition in Brazil, conducted in 2008-2009, was the first survey based on a nationwide representative sample to study the prevalence of diarrhea and associated factors among Indigenous children in the country. METHODS The survey assessed the health and nutritional status of Indigenous children < 5 years of age based on a representative sample of major Brazilian geopolitical regions. A stratified probabilistic sampling was carried out for Indigenous villages. Within villages, children < 5 years of age in sampled households were included in the study. Interviews were based on a seven day recall period. Prevalence rates of acute diarrhea were calculated for independent variables and hierarchical multivariable analyses were conducted to assess associations. RESULTS Information on diarrhea was obtained for 5,828 children (95.1% of the total sample). The overall prevalence of diarrhea was 23.5%. Regional differences were observed, with the highest rate being in the North (38.1%). Higher risk of diarrhea was observed among younger children and those who had less maternal schooling, lower household socioeconomic status, undernutrition (weight-for-age deficit), presence of another child with diarrhea in the household, and occurrence of upper respiratory infection. CONCLUSIONS According to results of the First National Survey of Indigenous People's Health and Nutrition, almost a quarter of Indigenous children throughout the country had diarrhea during the previous week. This prevalence is substantially higher than that documented in 2006 for Brazilian children < 5 years generally (9.4%). Due to its exceedingly multicausal nature, the set of associated variables that remained associated with child diarrhea in the final multivariable model provide an excellent reflection of the diverse social and health inequities faced by Indigenous peoples in contemporary Brazil.

Abstract
Objective: To systematize studies on the anthropometric nutritional status of Brazilian indigenous children in order to examine the ability to address the totality of biological, anthropological, and ecological aspects, as well as to characterize the main analytical results of the determinants of nutritional status of Brazilian indigenous children. Methods: MedLine and Lilacs were searched using the intersection of "South American Indians" and "nutritional status" descriptors (the search in MedLine also included the descriptor "Brazil"). Results: Overall, 65 studies were identified, and 23 were considered relevant to this study. The systematization of these studies highlights the concentration of studies in the midwestern and northern regions of Brazil, as well as the lack of cultural, biochemical, and food consumption approaches. Regarding nutritional status, we found: 1) greater vulnerability of younger children, especially in relation to stunting; 2) absence of differences in nutritional status according to sex; 3) socioeconomic determination of nutritional status; 4) differences in nutritional status between children from different villages. Conclusion: The nutritional status of Brazilian indigenous children is associated with age, socioeconomic status, and ethnic characteristics. Efforts are needed to understand the ethnic and cultural influence on nutritional status and on its causal network, as well as of various factors minimally discussed.

Abstract
INTRODUCTION The prevalence of undernutrition, which is closely associated with socioeconomic and sanitation conditions, is often higher among indigenous than non-indigenous children in many countries. In Brazil, in spite of overall reductions in the prevalence of undernutrition in recent decades, the nutritional situation of indigenous children remains worrying. The First National Survey of Indigenous People's Health and Nutrition in Brazil, conducted in 2008-2009, was the first study to evaluate a nationwide representative sample of indigenous peoples. This paper presents findings from this study on the nutritional status of indigenous children < 5 years of age in Brazil. METHODS A multi-stage sampling was employed to obtain a representative sample of the indigenous population residing in villages in four Brazilian regions (North, Northeast, Central-West, and Southeast/South). Initially, a stratified probabilistic sampling was carried out for indigenous villages located in these regions. Households in sampled villages were selected by census or systematic sampling depending on the village population. The survey evaluated the health and nutritional status of children < 5 years, in addition to interviewing mothers or caretakers. RESULTS Height and weight measurements were taken of 6,050 and 6,075 children, respectively. Prevalence rates of stunting, underweight, and wasting were 25.7%, 5.9%, and 1.3%, respectively. Even after controlling for confounding, the prevalence rates of underweight and stunting were higher among children in the North region, in low socioeconomic status households, in households with poorer sanitary conditions, with anemic mothers, with low birthweight, and who were hospitalized during the prior 6 months. A protective effect of breastfeeding for underweight was observed for children under 12 months. CONCLUSIONS The elevated rate of stunting observed in indigenous children approximates that of non-indigenous Brazilians four decades ago, before major health reforms greatly reduced its occurrence nationwide. Prevalence rates of undernutrition were associated with socioeconomic variables including income, household goods, schooling, and access to sanitation services, among other variables. Providing important baseline data for future comparison, these findings further suggest the relevance of social, economic, and environmental factors at different scales (local, regional, and national) for the nutritional status of indigenous peoples.

Abstract
The goal of this longitudinal study was to assess the impact of economic change and increased market integration on subsistence strategies, living conditions, growth, and nutritional status of Ribeirinhos living in the rural Amazon, Brazil. Data on weight, height, skinfolds, and circumferences, as well as data on economic strategies and living conditions were collected from 469 individuals in 2002 and 429 in 2009. Of these, 204 individuals were measured on both occasions. Independent and paired t-tests were used to identify changes in nutritional status over time in the larger sample and smaller, longitudinal subsample, respectively. Multiple linear regressions were used to examine the relationship between changes in economic/living conditions and nutritional status in the longitudinal subsample. Results indicate modest improvements in linear growth (HAZ) and among male children the observed increase was related to enrollment in the Brazilian conditional cash transfer program, Bolsa Família (P = 0.03). In terms of short-term measures of nutritional status, we found a significant increase in ZTSF and a reduction in ZUMA in most age/sex groups. Among subadults, there was a negative relationship between ZUMA and access to electricity (P = 0.01) and positive relationship between ZUMA and the sale of the açaí fruit (P = 0.04). Significant changes in weight and BMI (P < 0.01) were found among adult females and both were negatively related to household cash income (P = 0.02 and P = 0.03, respectively). Despite significant changes in economic strategies and lifestyle, changes in nutritional status were modest which may be explained by increased food insecurity documented during this early stage of transition.

Abstract
OBJETIVO: Avaliar o estado nutricional de crianças dos povos indígenas de famílias lingüísticas Aruak e Karibe do Alto Xingu, no Brasil Central, e verificar a associação entre os níveis de hemoglobina das crianças segundo sexo, idade e estado nutricional. Foram estudadas, no total, 470 crianças menores de dez anos de idade em 2001/2002. MÉTODOS: Para as crianças menores de cinco anos de idade, o diagnóstico de desnutrição foi realizado com base nos índices altura/idade e peso/altura, adotando-se como ponto de corte dois desvios-padrão aquém da média esperada para idade e sexo da referência - WHO, 2006. O diagnóstico de excesso de peso foi definido de acordo com o índice peso/altura acima de dois desvios-padrão da média esperada da mesma referência; as crianças com idade entre cinco e dez anos foram classificadas com baixo peso, sobrepeso ou obesidade de acordo com valores do índice de massa corporal, segundo sexo e idade, propostos por Cole e cols. O diagnóstico de anemia foi determinado a partir de concentrações de hemoglobina inferiores a 11,0 g/dL e inferiores a 11,5 g/dL para as crianças com idade entre 6 e 59 meses e entre 60 e 120 meses, respectivamente. RESULTADOS/CONCLUSÃO: Verificou-se entre as crianças indígenas elevada prevalência de déficit de estatura; a condição de baixo peso praticamente inexiste e o excesso de peso é expressivo entre as crianças mais novas e as de maior idade. A magnitude da anemia alcança cerca de 70% e a idade parece ser o principal fator associado às baixas concentrações de hemoglobina.

Abstract
A despeito da relevância do tema, as condições de alimentação e nutrição das populações indígenas no Brasil permanecem largamente desconhecidas. O presente estudo examina o caso de uma comunidade Wari', povo indígena localizado em Rondônia, no sudoeste amazônico. Foram realizados dois inquéritos antropométricos de modo a investigar a situação nutricional da população e analisar variações sazonais. Nos inquéritos, seis meses aparte, foram examinados 279 e 266 indivíduos com idades entre zero e 87 anos. As prevalências de baixa estatura (61,7%) e peso (51,7%) entre as crianças menores de cinco anos estão entre as mais elevadas já registradas na literatura sobre populações indígenas no Brasil. Sobrepeso e obesidade não são expressivos na população, seja qual for a faixa etária considerada. Os perfis antropométricos indicam condições mais desfavoráveis durante os meses de chuva, quando as prevalências de desnutrição em crianças aumentam e adultos de ambos os sexos apresentam menores médias de peso corporal. Aponta-se para a necessidade de se considerar a sazonalidade na definição de rotinas de vigilância nutricional e na discussão dos perfis de nutrição de povos indígenas.

Abstract
Apesar da proximidade dos grupos indígenas do Alto Xingu com a sociedade, os estudos têm mostrado adequação do peso para estatura e déficit de estatura para idade das crianças desses povos. Em relação aos adolescentes, pouco se conhece sobre suas condições nutricionais. O presente estudo teve como objetivo avaliar o estado nutricional de adolescentes Kamayurá, valendo-se de variáveis antropométricas. As medidas de peso, estatura, pregas cutâneas e circunferências corporais foram coletadas de 65 adolescentes, sendo 31 indivíduos masculinos e 34 femininos. As médias de estatura em relação à idade foram menores do que aquelas encontradas na Pesquisa Nacional sobre Saúde e Nutrição e na população de referência do National Center for Health Statistics. Houve taxa elevada de sobrepeso no sexo masculino (38,7%) e no feminino (23,5%); a obesidade foi encontrada em uma adolescente (2,9%). Nenhum adolescente com sobrepeso apresentou ambas as pregas tricipital e subescapular acima do percentil 90. Não houve casos de déficit nutricional em adolescentes de ambos os sexos. Apesar da alta prevalência de sobrepeso, o estado nutricional dos adolescentes em estudo é adequado, dada a baixa adiposidade.

Abstract
Se describieron las enteroparasitosis más frecuentes en dos comunidades Mbyá-Guaraní de Misiones, Argentina: Kaaguy Poty e Yvy Pytá. Las parasitosis intestinales se asociaron con el estado nutricional de los individuos infectados y los factores ambientales y culturales que caracterizan a las poblaciones estudiadas. Los resultados se compararon con los obtenidos en una población aborigen vecina, Takuapí, y la población urbana más cercana: Aristóbulo del Valle. Se utilizaron las técnicas de Ritchie, Willis y Kato Katz para las muestras fecales. Se analizaron los parámetros antropométricos y se procesaron muestras de tierra. De un total 296 individuos en las cuarto poblaciones, 100 (87,7%), 63 (88,7%), 49 (96,1%) y 50 (82%) estuvieron parasitados en Kaaguy Poty, Yvy Pytá, Takuapí, y Aristóbulo del Valle respectivamente. El 84% de los individuos parasitados estuvieron poliparasitados. El 43% de los individuos medidos presentaron desnutrición y el 87% de ellos estaban parasitados. Hubo asociación entre el uso de letrinas y Giardia lamblia (p < 0,01); defecación a cielo abierto, ausencia de calzado y ancilostomídeos (p < 0,01); el tipo de vivienda y los helmintos en general (p < 0,01). En el suelo se hallaron formas parasitarias, sugiriendo la relación entre la contaminación del entorno ambiental y la elevada prevalencia de parasitosis intestinales en las poblaciones estudiadas.

Abstract
Obesity is a worldwide public health problem impacting not only industrialized nations but also developing countries. The main objective of this paper was to analyze risk factors for overweight among Amerindian children and their mothers. Data were collected in 15 Amerindian riverside communities from the Beni River (Bolivia). The total sample was of 195 mothers and 452 children, 0-15 years of age. Information about family activity and dietary patterns was collected, and a clinical examination was performed. Stool samples were collected in children for parasitological screening. Anthropometric measurements, including weight, height, arm circumference, and four skinfolds, were taken. A bioelectrical impedance analysis was performed in mothers. In total, 12.2% (95% confidence interval (CI(95%)) 9.1-15.9%) of the children were considered overweight; less than 1% were overtly obese International Obesity Task Force (IOTF) criteria. Among their mothers, 35.3% (CI(95%), 28.7-42.5%) were overweight (BMI (weight/height (2)) >25 kg/m(2)), and 5% (CI(95%), 2.5-5.1%) were obese (BMI >30 kg/m(2)). BMI was moderately related to anthropometric indices of body composition in children, but was highly correlated with fatness in mothers. The risk of overweight was not associated with environmental factors in children. In mothers, there was a significant relationship between BMI, health status, and dietary diversity score. There was a moderate association in boys between fatness and the BMI of their mothers (R(2) = 0.12, P < 0.001), but not in girls. These findings suggest a trend toward accumulation of fat related to possible changes at the economic and agricultural levels, even in remote rural areas.

Abstract
Human herpesvirus 8 (HHV-8) seroprevalences were determined in two isolated Amazon Amerindian tribes, according to age, gender and familial aggregation. Plasma and serum samples obtained from 982 Amazon Amerindians (664 Tiriyó and 318 Waiampi) were tested for antibodies against lytic and latent HHV-8 antigens by using ‘in-house’ immunofluorescence assays. Overall, HHV-8 seroprevalence was 56·8 % (57·4 % in the Tiriyó tribe and 55·7 % in the Waiampi tribe). Seroprevalence was independent of gender and increased linearly with age: it was 35·0 % among children aged 2–9 years, 51·4 % in adolescents (10–19 years), 72·9 % in adults and 82·3 % in adults aged >50 years. Interestingly, 44·4 % of children under 2 years of age were HHV-8-seropositive. No significant differences in seroprevalence between tribes and age groups were detected. It is concluded that HHV-8 is hyperendemic in Brazilian Amazon Amerindians, with vertical and horizontal transmission during childhood, familial transmission and sexual contact in adulthood contributing to this high prevalence in these isolated populations.

Abstract
Fish are abundant and important dietary items for the Amer-Indians, and total hair-Hg (HHg) concentration is a reliable marker of fish consumption. We studied the impact of fish consumption (HHg) on the nutritional status of Indian children of Eastern Amazonia. Weight-for-height Z score (WHZ) was measured, and HHg was determined in 203 children younger than 10 years of age in three villages. There was significantly higher fish consumption in Kayabi children (16.55 microg Hg/g; SD, 11.44) than in children of the Munduruku villages of Missão-Cururu (4.76 microg Hg/g; SD, 2.09) and Kaburua (2.87 microg Hg/g; SD, 2.13). Anthropometric indices showed WHZ means of -0.27, -0.22, and 0.40, respectively, for Kayabi, Missão-Cururu and Kaburua villages. Despite a different pattern of fish-protein consumption between tribes, there was no significant correlation between WHZ and HHg concentrations (r2 = 0.0079; P < 0.2021). Dietary differences among Amazonian tribes can be traced and used in measuring health outcomes. Higher fish consumption, although important for Kayabis, was compensated by other protein sources by the Kaburua villagers.

Abstract
This study focused on the under-five population of the Alto Xingu region in Brazil, with the following objectives: (1) to evaluate height and weight increment from the first through the fourth years of life and (2) to compare nutritional status in 1980 and 1992. Height and weight increases were evaluated in 81 children. Weight and height were measured in 264 children evaluated in 1980 and in 172 in 1992 (< 10 years of age). Median Z-scores in the first and fourth years of life, respectively, showed: (1) a decrease in weight-for-age, (-0.12 in the first year and -0.51 in the fourth year of life; p = 0.002); (2) a decrease in weight-for-height (+1.31 and +0.08; p < 0.001); (3) an increase in height-for-age (-1.50 and -0.94; p < 0.001). Median Z-scores in 1980 and 1992 showed: (1) no change in weight-for-age (-0.61 in 1980 and -0.62 in 1992; p = 0.90); (2) no change in weight-for-height (+0.27 and +0.34; p = 0.10); and (3) a decrease in height-for-age (-1.04 and -1.22; p = 0.02). Height-for-age increased and weight-for-height decreased between the first and fourth years of life. A decrease in height-for-age was observed from 1980 to 1992, demonstrating the importance of nutritional surveillance among the population of the Alto Xingu.

Abstract
Growth and nutritional status of children and adults in two Mbyá-Guaraní communities from Argentina, was assessed. Height, weight, sitting height, upper arm circumference, triceps and subscapular skinfold were measured on 120 individuals aged from 2 to 60 between March and May, 2001. Data were transformed to z-scores using United States references (NHANES I and NHANES II). A z-score of less than -2 was used as the cut-off point to determine the prevalence of stunting and wasting respectively. Mean z-scores for weight, height, and upper arm circumference lie below the reference (0 > Z > -3), while in sitting height ratio and muscular area for females they were above the US standard (0 < Z < 2). Skinfold thicknesses and muscular area for males were similar to the reference (2 > Z > -1). Our findings are in agreement with others South American Indian research that the prevalence of stunting (36.7%) is significantly higher than wasting (1.8%). The presence of parasitic infections and nutritional environment previously described in this population could be related to the short stature.
